Question #a87b0

Answer 1

Strong Base collection => Group IA and Group IIA Hydroxides (Except for Beryllium Hydroxide) can be titrated with strong acid such that concentration of Alkali-Hydroxide = concentration of Hydroxide ion in solution & indicates 100% dissociation.

Explanation:

Starting with say 1.0 mole/Liter NaOH in aqueous solution and titrating to end point with strong acid ( ~HCl(aq)) gives concentration of the Hydroxide ion `(OH^-)` in solution to equal 1.0 moles/Liter. Such is the starting amount of NaOH measured and dissolved into solution.

That is, for `NaOH(aq) => Na^+(aq) + OH^(-)(aq)`

`[OH^-] = [NaOH]` at end point & indicates 100% dissociation.
